TAKE-UP MECHANISM FOR NARROW-WARE LOOMS.

SPECIFICATION forming part of Letters Patent No. 494,755, dated April 4,1893.

` Application filed September 29, 1892. Serial No. 447,278 (No model.)

To aZ whom t may concern;

Be 1t known that I, ERNEST BURGESS, a citizen of the United States,residing at Paterson, v

in the county of Passaic and Stateof New Jersey, have invented a new anduseful Improvement in Take-Up Mechanism for Narrow-Ware Looms, of whichthe following is a specication.

My invention relates to improvements in looms, of the class known asnarrow-fabric or narrow-ware looms, and refers particularly to that partof the mechanism which receives and guides the ribbon or other fabricprevious to its being deposited in the cradle, and known as theknee-roll.

The object of my invention is to provide a knee-roll capable of holdingand drawing the ribbon or other fabric from the weavin g mechanism anddepositing it in the cradle without aliowing it to be reeled upon theroll, the objection to the latter being that the accumulation of fabricupon the knee-roll causes the picking mechanism to pick the ribbon atgradually increasing intervals instead of evenly or at regularintervals.

A further object of my invention is to provide simple, efficient andeasily operated means for adjusting the knee-roll upon its shaft, totake-up and let-ont the fabric when the latter becomes too loose or tootant, as the case may be.

A further object of my invention is to provide means to adjust thetension of the friction or feed-roll by which theribbon is held incontact with the frictional surface of the knee-roll.

Further objects and advantages of my invention will appear in thefollowing description, and the novel features thereof will beparticularly pointed out in the appended claims.

In the drawings: Figure l is a perspective View showing the middlecasting or bracket of a loom, the knee-roll shaft (a portion thereof)and one of the adjustable knee rolls mounted thereon. Fig. 2 is alongitudinal vertical section through the linee-roll and bracket takenin the plane of the shaft. Fig. 3 is a detail inside view of the rotaryadjusting disk; and Fig. 4 is an end view of the knee-roll, with the adjusting disk removed and the hub'partly broken away, showing the setscrewand adjusting-pinion which is loosely mounted upon thesquared shank ofsaid screw.

Referring by letter to the drawings, A designates the knee-roll shaft,constructed, arranged and mounted as in other looms of this class, thesame passing at an intermediate point through the intermediate bearing,d, which is formed upon the middle casting or bracket, B. The box, A',in which saidbearing is formed is forwardly and rearwardly adjustable bymeans of an adjusting-bolt, c', which takes in a horizontal slot, A, inthe casting or bracket. The other bearing boxes at opposite ends of theloom frame, in which this knee-roll shaft is mounted, (said bearings notbeing shown in the drawings) are provided with similar means for forwardand rearward adjustment.

Orepresents a horizontal feed-roll supporting-shaft, parallel with theknee-roll shaft, which is loosely mounted at an intermediate point in abearing, d, in the upper end of the standard, D, and at its ends insimilar bearings in the ends of the loom-frame. This standard, D, isforwardly and rearwardly adjustable to move the feed-roll shaft, and issecured at its lower end to a horizontal bar, A', of the middle castingor bracket, said bar being provided with a horizontal slot, e, toreceive a transverse bolt, el', which engages the vertical slot, e', inthe lower end of the standard. By means of these intersecting slots andthe adjusting bolt, the standard is capable of vertical as well asforward and rearward adjustment with relation to the knee-roll shaft. Itis obvious that the bearings for the extremities of this shaft must becapable of similar adjustment, but as the forms of adjustable or slidingbearings are numerous, and as my invention relates solely to thatportion of the mechanism which is directly connected with the knee-roll,l will conne myself in this description, to the construction of themiddle casting or bracket, the bearings and attach ments carriedthereby, and one of the knee-rolls carried by the kneeroll shaft, itbeing understood that a series of these rolls extending from one end ofthe shaft to the other (and all constructed as herein specified) isemployed. Only one intermediate or middle cast-ing or bracket isnecessary, as will appear from the following description.

The feed-roll shaft being loosely mounted in its severalbearings, asabove specified, it

is capable of rotary adjustment to accomplish which I attach rigidlythereto the upper end of the tension-adjustinglever, E, thelower end ofwhich is longitudinally slotted, as shown at f, to register with theyhorizontal -slot orv slots, f, in the transverse bar, G, of the eastingor bracket, an adjusting bolt, F, engaging.V said slots to lock thelevei at the desired adjustment. Mounted loosely upon the knee- 1011shaft is the knee-roll, H,.provided with a.

is mounted looselyupon the shaft, and at the other end -by a.head-plate, L, which `is fixed tothe rolland is `provdediwith a hub, Z,which, also, is looselym'ountedupon the shaft. hub, Z, extends inwardfrom the head-plate and is'provided with a radialtapped socket, fm, inwhich fits and operates a set-screw, M, having a squared or` angularshank,M. The head-plate is cu t-awayor recessed at L and in this recessstands a beveled adj Listing-pin,- ion, N, having a squared or angularbore, n, to receive and slidezupon the shank o f the set-screw. It willbe noted that this .adjustingpinion-is held againstlateral movement bythe Walls of the recess in which .it is arranged and-being fitted uponthe shankof :the set-screw is capable of rotatontherewith, thelongitudinal movement of the screw duri-ng said rotationnot affectingthe position. of the pinion.

Secured `to the outer end of .thehub carried by the head-plate isacollar, O,whichis held-in place byscrews taking into thehub, and mountedloosely upon the hub, between the collar and the adjacent side of thekneerollis arotary adjusting wheel or disk, P, provided upon its innersurface with an annular gear,.Q, which meshes withthe teethrof theset-screw pinion.

The radial socket in which the set-screw is itted extendsto andcommunicatesv with the bore o f thehub, whereby when the set-screw isscrewed inward it will bind or engage the shaft and lock the knee-rolllirmly'thereto. Therefore,by turning the adjusting wheel or disk,whichis connected by gearing to `the set-` screw, the knee-roll may belocked flrmlyto the shaft, or loosened therefrom, at will to perv mit'the desired adjustment of said -roll in taking-up-slack of the fabricorletting-out the same.

The loose disk and the adjusting disk are arranged-as will be seen, atoppositeends of the knee-roll, and extend at their peripheries beyondthe saine to forni guards or ianges to prevent the fabric fromslippinglaterally.

A yoke, R, is connected to the feed-rollshaft` by means of-spring-coils,r r, preferably formed integral with the-arms, r" fr', of the yoke, the

The

'knee-roll may be regulated 'at the will of the operator.
